check engine light on on 2001 Oldsmobile Aurora

I sent my 2001 Aurora to strauss Auto for it to be diagnosed about the check engine light that has popped up a few days ago and they came up with the following:1. P0410-secondary air injection system2. P0141-02 sensor, bank 1 sensor 2.3. P0300-engine misfire detected4. P0463-fuel level sensor circuit open/bad

I want to have an estimate of how much it will cost me to fix these problems. They do not undertake servicing of those problems there. Get back to me ASAP. Phone number: 848-468-6114

410 is the air pump and/or circuit failure. this system works on initial start up to burn unburnt fuel when cold in the exhaust manifold. as far a price, you need to find out what part failed and why. you need a real diag for this.141 is the heated o2 sensor failure. in most cases, the sensor is bad. the sensor is about 79 at an aftermarket parts store and .8 hours to replace.463 indicates to return voltage from the sender unit. in most cases, the pump module is the failure. the module is around 300 with 2.5 hours labor.

300 is a missfire detected on multiple cylinders. it could be plugs and/or coils. once again a diag is needed to determine the real failure and a bid.

Yeah gl with all of that. I have a 2001 and First time I had it tested on the computer it said my o2 sensors was bad. Took it to another garage two days later and it come up as the crank shaft sensor and the cam sensor and the secondary air unit. The garage took the air unit out and tested It and it works fine. Put it back in the car and it don't work. Have power to the relay but not to the unit. Same with all my windows. Only window that works is the driver door. all the rest I have to unplug the power to the motor and cross wires to get them to go up and down. There is a major Elc problem with these cars and the GM dealer is to stupid to figure it out. I have done lots of reading about the air unit and almost every car the dealer has replaced them on have Melted and burned out again within hours of leaving the dealer. I also had the missfire detected on multiple cylinders code come up before and never replaced anything and guess what. That code was a different one a day later.
